Demi Lovato has had a turbulent year, but her triumphant return to the spotlight and the success of her latest album, 'Unbroken,' has her riding higher than ever. But that doesn't mean that all her wounds have completely healed. In a new interview with Parade, Lovato says that she's gotten burned by making herself too vulnerable. "Sometimes you don't know who you can and cannot trust," she says. "I still learn that over and over again."

The chanteuse recently announced her upcoming tour in promotion of the album — a tricky subject, given that her very public derailment occurred during her last major tour. But Lovato says she's stoked to be touring again, showing her skills on the piano and guitar as well as dancing to her well-loved uptempos. She's also confident that she can manage the intense pressures of travel with more serenity. "I'm in a much happier and healthier place now," she says, "so I'll be able to decide when I need time off. It's a different era in my career. I'm sure that if I need time off I'll be able to speak about it and I'll take a step back."

It certainly can't hurt to have the support of her Lovatics, who have enthusiastically embraced her comeback after Demi decided to come clean about the issues with which she'd been struggling. "I just realized that once I went into the treatment center," she explains, "pretty much anything and everything was going to come out anyway. At the same time, I wanted to help other people who shared my issues." That seems to have paid off; Demi says, "Some of my fans have said that because I've been able to speak about my issues, that they're not afraid to speak about theirs, which is an amazing feeling."

'Unbroken,' which was released on Sept. 20 to mostly positive reviews, has been a chart success for Lovato, peaking at No. 4 on the Billboard 200 albums chart. The album marked a dramatic sonic shift for Lovato, away from the pop-rock of her previous work and into more dance/R&B territory. She has yet to announce the follow-up single to epic ballad 'Skyscraper.'
